In a transverse wave, the key characteristic is that the vibrations occur perpendicular to the direction of energy propagation. This means that if the wave is moving horizontally, the particles of the medium responsible for the wave oscillate up and down. This perpendicular relationship is fundamental to how transverse waves, such as light waves or waves on a string, propagate energy through a medium.

The other concepts do not apply to transverse waves. Vibrations occurring along a line suggest a longitudinal wave, where the vibrations are parallel to the direction of wave travel. The presence of compressions and rarefactions is specific to longitudinal waves, which involve the dense regions (compressions) and less dense regions (rarefactions) resulting from particle displacement in the same direction as wave travel. Finally, the idea of vibrations canceling each other out typically relates to interference patterns rather than defining the nature of the wave itself. Therefore, the definition provided correctly identifies the unique characteristic of transverse wave motion.
